Cygnus X–Star Complex

and you thought this was going to be easyCygnus X is mind-boggling in a bunch of ways. First, as always, is the astounding image returned by a space telescope, in this case the Spitzer Space Telescope, an infrared earth-orbiting observatory. Then there is the issue of what we are actually looking at: Cygnux X, as it turns out, is a star-factory or star-nursery, that is, a region of space that produces new stars out of clouds of interstellar gas and dust. Impressive, to be sure, but here is something even more impressive: Cygnus X contains NML Cygni, the largest star known. NML Cygni is 1,650 times as large as our sun; its radius is 7.67 astronomical units across. That’s right; if NML-C was our star, we would lie well within its surface. Cygnus X contains other massive protostars and lies 4,600 light years from earth.   RT

    Impressive and mind-boggling facts are my favorite kind.

    This is a magnificent image – it reminds me of the marbled pages you’d find inside of old Victorian books.

    On the other hand it looks like a mass of Christmas-colored nerve endings, ready to spark and create a new star!
